[00:00:00]Mercury, the innermost planet, [music] experiences extreme temperature swings due to its proximity to the sun and lack of atmosphere. On the night side, temperatures plummet [music] to a bone-chilling minus 180° C, freezing the surface solid. Without an atmosphere to trap heat, the sunless side rapidly [music] loses warmth, reaching these frigid extremes.

[00:00:24]As Mercury rotates slowly, the terminator [music] zone marks the dramatic shift from eternal night to scorching day. [music] In direct sunlight, surface temperatures soar to over 430° C, hot enough to melt lead.

[00:00:40]The intense solar radiation bakes the regolith, causing rapid expansion [music] and surface fracturing under extreme heat. These swings happen over one Mercury day, which lasts 176 Earth [music] days, amplifying the contrasts.

[00:00:55]No insulating atmosphere means heat escapes instantly [music] at night, but absorbs brutally during the long solar day.

[00:01:03]This creates the widest [music] temperature range of any planet, from minus 180 to plus 430° C. C.

[00:01:12]Mercury's [music] harsh extremes showcase the raw power of our solar system's innermost world.
